Designed, manufactured and built in the U.S.A., the Xi-Mill is a high performance raised bed, elevated carriage machining center that meets the needs of companies wishing to high speed mill a wide range of parts and materials. It gives the user the flexibility to manufacture smaller parts and gang fixtured parts in "Dual Work Zone" mode or by switching to "Single Work Zone" mode the ability to manufacture long parts with the cutting dynamics of a small machine. The X travel starts at 157" (4.0m) and is available with travels up to 255.6" (6.5m); the Y and Z stroke is 20.0" (500mm). The X-Mill high velocity machine that traverses at 2400 ipm (60 m/min), feeds to 1181 ipm (30m/min), accelerates at 0.5g and has a 30hp (22kW) 15,000 rpm spindle. The moving 3 axis spindle module is mass minimized and built for high rate machining. The "Tool Centered Feed Force" design arrangement centers the axis feed force "line of action" on the cutting tool. The machine incorporates a number of Lean Manufacturing concepts that allows the machine to be quickly reconfigured to perform multiple tasks. A single machine can handle virtually all the needs of any shop that needs to manufacture a wide variety of product on a single machine. For High Volume Production, a "Twin 3 Axis Module, MM" Option is available for 3x3 machining. Two Moving Modules can each machine parts independently in each work zone or in tandem using two spindles to machine a single part.
